OK, but Guix seems to have decided on numbering in the past, I don't 
think a package patch is a place to change that policy. If you want to 
change things to calendar versioning for some kinds of git stuff, this 
sounds like something to be discussed and approved or disapproved on 
guix-devel@gnu.org, not here.

As mentioned later, "guix refresh -u" != automatic updates. I expect 
that a person manually updating the package would prefer the aid of 
"guix refresh -u" instead of having to clone the git repo by theirselves 
and do "guix hash -r", maybe forget the "-x", then remembering that "-r" 
is deprecated then having to look in the manual for --serializer=nix.

Guix does not have automatic updates, it does not decide by itself to 
update some packaes without any review. The updaters are only run when 
done so manually, e.g. with "guix refresh -u fortunes-jkirchartz". In 
that case, as always though it seems to be neglected due to limited 
resources currently, the diff between the previous version and the new 
version should be verified for malware.  There's no X trumps Y here, AFAICT.

Also, if Guix decides on CalVer for some packages, then in the context 
of the latest-git updater, the latest-git updater will have to be 
modified to support CalVer -- latest-git has no idea about how 
individual packages work, so it cannot decide to block updates. As such, 
going for CalVer to prevent generic-git from updating (with guix refresh 
-u or --with-latest) does not seem robust to me, as it will just be 
updated anyway with future improvements to latest-git.

If you want to block updates to some degree for some packages, then you 
could look into, say, adding a (updatable? . #false) flag or such for 
the 'properties' field or maybe add a comment next to the package 
definition to ask people updating the package to look out for 
fortunes-mod-style badness.

Greetings,
Maxime.
